PROCESS OF DRYING STOCKINGS ON FORMS.

Application filed February 19, 1921.

To all whom it may concern.

Be it known that I, CHARLES W. Scr-nvanrz, Jr., a citizen of the United States, residing in Philadelphia, Pennsyl- Vania, have invented certain Improvements in Processes of Drying Stockings on Forms, of which the following is a specification.

One object of my invention is to provide means for drying stockings 011 forms and at the same time to prevent, to a certain degree,

I Fig.1;

Fig. 5 is a sectional view on the line 55, Fig. 1;

Fig. 6 is an exaggerated view, showing the stocking fabric drawn into the perforations of the form;

Fig. 7 is a view showing the perforations at one end only of the form; and

Fig. 8 is a diagrammatic sectional view illustrating a form within a drying chamher.

In carrying out my invention, I provide a form such as described and claimed in an application for patent filed by Walter M. Schwartz of even date herewith, serial No. 215,872. This form is made of metal and is hollow, as shown in the sectional view, having thin side members shaped to conform to the shape of a stocking. These members are spaced apart and are connected by braces, or rivets, 2. The edges of the side sections are secured by rivets 3, although it will be understood that the form may be made in any manner without departing from the essential features of my invention.

The lower end of the form is connected to a pipe 4 to which is attached a suction Specification of Letters Eatent.

pump, or fan, shown in diagram, as at 5. The form is perforated, as at 6. In some instances. it may be perforated at the toe section, as at 7. In fact, in the form shown in Fig. 1, the perforations are arranged so as to be opposite the reinforced portion of the stocking, such as the foot portion and the knee portion. In some instances, the form may be perforated throughout its length, or it may be perforated only at the bottom, as shown in Fig. 7, or at the open end of the stocking.

In carrying out my invention, the air is sucked through the stocking and inthis sucking operation the fabric of the stocking a, F ig. 6, is drawn into the perforations 6, so that the tendency is to hold the stocking firmly on the form while being dried,

materially reducing the shrinkage of the fabric. It is desirable, in many instances, to prevent shrinking at the foot. This can be accomplished in the same manner, as the fabric will be drawn into the perforations at the foot in the same way, as shown in Fig. 6.

The form may be enclosed in a drying chamber 8, as shown in diagram, Fi 8, in which are steam pipes 9, or into w ich hot air may be introduced. Means may be provided for moving the stocking form into and out of this chamber. Any of the ordinary stocking drying machines may be used without departing from the spirit of the invention.

lVhile I have described my process particularly in connection with drying stockings, it may also be used in drying other garments, which are liable to shrink in drying.

1 claim- The process herein described of preventing shrinking of knitted stockings and like garments of relatively elongated tubular form while being dried, said process consisting in placing said garment on a form which is perforated near the open end of the garment, then causing air to be drawn into the form and through the walls of the garment, causing the fabric of the garment to be drawn into the perforations thus preventing material shrinkage of the fabric while the garment is on the form.

I It is hereby certified that in Letters Patent No. 1,411,876, granted April 4, 1922, upon the application of Charles W. Schwartz, Jr., of Philadelphia, Pennsylvania, for an improvement in Processes of Drying Stockings on Forms, an error appears in the printed specification requiring correction as follows: In the heading to the printed specification, line 6, for the Words Application filed February 19, 1921. Serial No. 446,356. read Application filed August 7, 1919. Serial No. 316,004.; and that the said Letters Patent should be read With this correction therein that the same may conform to the record of the case in the Patent Office.
